Here are some other tips from this insanely great article FULL of ideas for NYC's best stylists:

If you find yourself caught in a freak rainstorm, never fear. To save your wave, simply throw hair up in a quick braid, Temur of Sharon Dorram Color at Sally Hershberger tells me. You can let it down for magically re-waved hair. Or, just leave it braided. "Humidity can actually make braided hair styles look even better, because humid air will make hair more puffy and big, which makes braids look more full," he says.

If you did apply makeup — even if it was just tinted moisturizer and a touch of mascara — be sure to finish off your handiwork with a settingspray. It'll help keep your look in place, despite the fact you'll be walking through a wall of water. It works by creating a barrier between the environment and the makeup, freelance makeup artist Jeannie Giannone tells me.

So really, there's nothing to worry about when the weather turns bad. You can, with a little effort, have great looking hair and makeup on even the rainiest of days.
